Definitions

  • the present invention relates to a method of measuring a diameter of a roll in a roll grinder, which will be referred to "roll diameter" hereinafter, and an instrument for measuring the roll diameter in the roll grinder. More particularly, it relates to the measuring method and instrument for correcting variations of measurements of the roll diameter due to changes in temperature automatically.
  • a measuring of the roll diameter has been carried out by interposing the roll above the roll grinder between a pair of movable gauge heads as roll diameter measuring means, which are mounted on a carriage so as to reciprocate in the axial direction of the roll.
  • the roll grinder further includes a master bar attached thereto, of which dimension has been previously known. Prior to measuring the roll diameter, the dimension of the master bar is firstly measured by using the above roll diameter measuring means. Thereafter, the measurements by the roll diameter measuring means are calibrated by the above roll diameter detected by the roll diameter measuring means.
  • the measurements of the roll diameter would be corrected by the above correction value derived from the only basic dimension of the master bar, irrespective of largeness of roll diameter. Therefore, when the roll diameter as the measuring object is close to the basic dimension of the master bar, it is possible to correct the measurement with high accuracy. To the contrary, when the roll diameter is far from the basic dimension, the correcting accuracy for the measurement of the roll diameter is influenced since such a roll diameter causes an increase of the content of movement error of the movable gauge heads of the roll diameter measuring means in the diametrical direction of the roll.
  • Another problem resides in that the heat capacity of the master bar is remarkably small in comparison with the heat capacity of the roll.
  • the master bar is disposed under the similar temperature condition as that of the roll on the roll grinder, there would be produced a difference in dimensional changes between the master bar and the roll due to the difference in heat capacity therebetween, so that it is impossible to obtain an appropriate correction value, thereby limiting the accuracy in correcting the measurement of the roll diameter.
  • the object of the present invention described above can be accomplished by a method of measuring a roll diameter of a roll mounted on a roll grinder having roll diameter measuring means for measuring the roll diameter, the method comprising steps of:
  • preparing a step-shaped conical master roll consisting of a plurality of diametrical parts arranged coaxially, respective diameters of the diametrical parts being different from each other;
  • the roll diameter measurement is corrected by the correction value brought by the diametrical part of the master roll closes to the roll diameter. Since the master roll is shaped to have the plurality of diametrical parts different from each other thereby providing a stepped conical configuration, the heat capacity of the master roll is remarkably large in comparison with that of the above-mentioned master bar, being closer to the heat capacity of the roll to be measured. Consequently, it is possible to decrease a reduction in correcting accuracy against the measured roll diameter, which is depending on the difference in heat capacity between the master roll and the roll.
  • the measuring step of the one diametrical part of the master roll and the calculating step of the correction value are executed every measuring of the roll diameter of the roll.
  • the measuring step of the one diametrical part of the master roll and the calculating step of the correction value are executed when an environmental temperature about the roll grinder changes over a predetermined value.
  • the measuring step of the one diametrical part of the master roll and the calculating step of the correction value are executed when time has passed over a predetermined value.
  • an apparatus for measuring a roll diameter of a roll mounted on a roll grinder having a carriage so as to reciprocate in the axial direction of the roll, a grinding wheel head mounted on the carriage and a work mounting bed for mounting the roll thereon, the apparatus comprising:
  • roll diameter measuring means for measuring the roll diameter of the roll, the roll diameter measuring means being mounted on the carriage and having movable gauge heads;
  • a step-shaped conical master roll arranged in alignment with a center axis of the roll mounted on the work mounting bed, the master roll having a plurality of diametrical parts of which diameters are different from each other;
  • standard diameter value storing means for storing standard diameters values of the diametrical parts, the standard diameters values being obtained by measuring respective diameters of the diametrical parts of the master roll under a condition of a predetermined temperature
  • roll diameter measurement correcting means for calculating a difference between a diameter value of one of the diametrical parts, of which standard diameter value is closest to the roll diameter value of the roll, measured by the roll diameter measuring means and the standard diameter value stored in the standard diameter storing means as a correction value, and correcting the roll diameter value of the roll, which is measured by the roll diameter measuring means, by the correction value.
  • the diameters of the respective diametrical parts of the master roll are measured by the roll diameter measuring means. Further, by the roll diameter measurement correcting means, the difference between the diameter of the diametrical parts of which standard diameter is closest to the roll diameter of the roll and the standard diameter stored in the standard diameter storing means is calculated as the correction value, so that the roll diameter of the roll is corrected by the correction value.

  • FIG. 1 to have a main spindle 11, a footstock 17 arranged on the work mounting bed 9 so as to be displaceable in the direction of Z-axis and provided with a work center 15, and neckrests 19 arranged on the work mounting bed 9 between the headstock 13 and the footstock 17.

  • a roll diameter measuring instrument 23 is attached to the carriage 3 through an arm 21.

  • the cross rail 25 extends in the direction of X-axis on the work mounting bed 9 horizontally.
  • a master roll 33 Arranged on the back side of the footstock 17 is a master roll 33 which is fixed on the right end of the work mounting bed 9 of FIG. 1 through a bracket 31 in the form of yoke.
  • the master roll 33 which includes a plurality of diametrical parts 33a, 33b, . . . coaxially arranged to form a stepped conical configuration, is arranged in alignment with the center axis C of the roll above the work mounting bed 9.
  • Both ranges of maximum and minimum diameters of the diametrical parts 33a, 33b, . . . are determined corresponding to the measurable extent of the roll diameter measuring instrument 23 and each diametrical pitch among the parts 33a, 33b, . . . is established in accordance with the required accuracy.
  • the measurable extent of the roll diameter is from 100 mm to 1000 mm, it would be preferable of 50 to 100 mm in diametrical pitch.

  • the roll diameter measurement correcting means 37 further corrects the roll diameter measurement, which has been measured by the instrument 23, by the above correction value.
  • the diameters of the respective diametrical parts 33a, 33b, . . . of the master roll 33 are measured under a condition at a predetermined "standard" temperature, so that the standard diameters of the parts 33a, 33b, . . . can be obtained and then stored in the standard diameter storing means 35.
  • a diameter of one diametrical part, of which standard diameter is closest to the roll diameter is measured by means of the roll diameter measuring instrument 23. Then, a difference between the so-measured "master roll" diameter of the above diametrical part and the above standard diameter is calculated as a correction value and thereafter, the roll diameter measured by the roll diameter measuring instrument 23 is corrected by the correction value. Consequently, it is possible to obtain the precise absolute dimension of the roll diameter irrespective of largeness of the roll diameter.
  • the measuring of the diametrical part of the master roll 33 and the calculation of the correction value have only to be carried out every measuring of the roll diameter or executed when the temperature varies over a predetermined value (e.g. b: constant) or when time has passed over another predetermined value (e.g. a: constant).
  • FIG. 4 is a flow chart of master set routine by which the correction value is set against each of the diametrical parts 33a, 33b, . . . of the master roll 33.
